Description
In the recent years the major developments in Loop
Quantum Gravity have arisen in the covariant framework
(spinfoam) where the dynamics is coded by transition
amplitudes. These provide an evolution for "quanta of
spacetime" in terms of a local product of interaction
vertices, reconstructing a Lorentzian spacetime. The first
part of the talk will be devoted to a general presentation
of these results. The second part of the talk will show
how these results find a good testing framework in
cosmology and how, viceversa, spinfoam could provide a
fertile framework for the description of the early-
universe physics.
